Core Web Vitals Checker

Good scores are: LCP under 2.5 seconds, FID under 100 milliseconds, and CLS under 0.1. Our tool shows these thresholds and provides specific improvement recommendations.

Scores can fluctuate based on server performance, content changes, and user interactions. We recommend weekly monitoring and immediate testing after any site changes.

Yes, Core Web Vitals are official Google ranking factors as part of page experience signals. Poor scores can negatively impact your search rankings, especially for competitive keywords.

LCP (Largest Contentful Paint) measures loading speed, FID (First Input Delay) measures interactivity, and CLS (Cumulative Layout Shift) measures visual stability. Together they represent complete user experience.

Optimize images, upgrade hosting, use a CDN, minify CSS/JavaScript, remove unnecessary plugins, optimize fonts, and prioritize above-the-fold content loading to improve LCP scores.

CLS is caused by elements shifting during page load. Fix by setting image dimensions, reserving space for ads, avoiding dynamic content insertion, and using CSS transforms instead of changing layout properties.

FID measures how quickly users can interact with your page, while load time measures when all resources finish loading. A page can load quickly but still have poor interactivity.

Yes, Google primarily uses mobile Core Web Vitals for ranking. Mobile scores often differ from desktop due to slower connections and less powerful devices, making mobile optimization crucial.

Google typically takes 2-4 weeks to reflect Core Web Vitals improvements in rankings. The tool uses a 28-day rolling average, so consistent good performance is essential.

Yes, third-party scripts often significantly impact Core Web Vitals. Audit and optimize analytics, chatbots, social media widgets, and advertising scripts for better performance.

Poor Core Web Vitals lead to higher bounce rates and lower user engagement. Studies show that improving these metrics typically results in better user retention and conversion rates.

Focus on the metric with the worst score first, prioritize pages with high traffic or conversion value, and implement fixes that impact multiple metrics simultaneously for maximum efficiency.
